"""
Shared fixtures and configuration for the DocGenie API test suite.

All tests target the deployed HuggingFace Space:
    https://text-to-document-generation-docgenie-api.hf.space

The /generate/pdf and /generate/async endpoints both require a valid
`request_id` that exists in the Supabase `document_requests` table.
Since we are exercising the *deployed* API (read-only from our perspective),
tests that need a request_id receive a FAKE UUID — this intentionally
surfaces the 404 path (which is a valid functional test for those endpoints).
The suite is designed so every test is safe to run repeatedly.
